When the electronic wire harness with high fire resistance is used, the fire resistance of the electronic wire harness is improved by the chlorinated rubber and paraffin in the fireproof coating, the glass fiber and calcium carbonate in the fireproof plastic layer, and the aluminum foil in the heat insulation layer, and the conductive silicone rubber in the antimagnetic shielding layer is used to prevent the electronic wire harness from being interfered by electromagnetic waves, thereby preventing the fire from spreading through the electronic wire harness, thereby improving the fire resistance of the electronic wire harness, and preventing the electronic wire harness from moving left and right and interfering with each other through the limiting mechanism, thereby facilitating the guide limit and preventing the electronic wire harness from interfering with each other.
